SHEET-METAL-SEAMING MACHINE.

SPECIFIGATION formihg part of Letters Fatent N0.610,558, dated September 13, 1898. Application filed October 7', 1897- $eria1No. 654,334. oio'moaem To all whom it mctyconcern:

Be it known that I, EDWIN NORTON, a citizen of the United States,residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sheet-Metal-Seaming Machines, of which the following is a specification.

My invention relates to sheet-metal-seaming machines intended for seaming the covers on sheet-metal cans, and more particularly to certain improvements upon the machine shown and described in Letters Patent No. 546,468, granted to F. E. Heinig September 17, 1895.

The object of my invention is to improve and perfect said machine and increase its capacity, so that the work may be done more perfectly, rapidly, and cheaply.

With this'object in view I combine with a clamping-ring made in two or more openingand-closing parts (and herein my invention consists) mechanisms for automatically opening and closing the parts of said clampingring, a revolving sleeve or frame furnished with antifriction rollers or wheels adapted to travel on the upper edge of said clampingring, and seaming-rollers 'journaled on operating-levers pivoted to said sleeve or frame and operated by a reciprocating block or head to press the seaming-rollers against the can head flange into operative position. The opening-and-closing parts of the clampingring may be produced in any suitable manner; but I prefer to form them not by dividing the clamping-ring into two or more opening-and-closing segments, but simply by cutting or splittingthe clamping-ring at one point, so that the opening andclosing of the clamping ring to receive, clamp, and release the can may be 'efiected simply by separating or drawing together the two meeting ends of the split ring.

My invention further consists in the novel construction of parts and devices and in the novel combinations of parts and devices here in shown and described and forming the subject of the claims herein.

In the accompanying drawings, forming a part of this specification, I have illustrated at Figures 1, 2, 8, 4, 5, and 6 a machine embody ing my invention, Fig. 1 being a side elevation, Fig. 2 a central vertical section, Fig. 3 a detail back end elevation, Fig. 4. an enlarged detail sectional view taken at right angles to the section of Fig. 2, Fig. 5 a detail elevation of the mechanism for opening and closing the split clamping-ring, Fig. 6 a detail plan of the split clamping-ring. Fig. 7 is a sectional view of the can and cover after being seamed by the machine, and Fig. 8 is a detail plan view of the clutch.

In said drawings, A represents the frame of the machine, and B the opening-and-closing up and down reciprocating clamping-ring, the opening-and-closing parts of which are preferably formed, as before stated, by splitmoved therefrom, it is mounted upon a ver-' tically-reciprocating slide, yoke, or frame 0, that moves up and down in suitable guides G on the frame of the machine. The clampingring Bis provided at opposite points of its circumference with projecting arms B, connected to the reciprocating slide 0. The two separate meeting ends or parts of the opening-and-closing clamping-ring B may be antomatically forced together or separated to clamp or release the can by any suitable mechanism, but preferably by means of a lever D, connected by a pivot d to one of the meeting ends 13 of the clamping-ring and which is fu'rnished'with an incline or cam slot 61, that engages a pin or projection 11 on the other meeting end B of the clampingring. The lever D is preferably pivoted to the frame of the machine at d by a pivot-pin d carriedby a bracket'd that is attached to the frame and is automatically operated to open and close the clamping-ring B by the reciprocating or up-and-down movement of the clamping-ring itself.

F F are the seaming-rollers, the same being preferably four in number, although a greater or less number may be employed. These seaming rollers are journaled upon movable levers or arms F, which are connected by pivots f to ears 9' on a revolving ring or sleeve G, which serves to rapidly revolvethe seaming-rollers around the axis of said ring and inside the clamping-ring B. The seaming-rollers F are forced out against the flange 00 of the can-cover X by means of a reciprocating op'eratinghead H, which is furnished with an annular groove h, in which fit the inner arms f of the seaming-rollercarrying levers F. The ring or sleeve G is provided with antifri-ction rollers g, that travel upon the upper edge b of' the openingand-closing clamping-ring B. The arms B on the clamping-ring B are provided with holes b, through which pass the guide-pins c on the yoke or bracket 0 secured to and forming part of the slide 0, so that the slide may have a slight up-and-down movement independent of the clamping-rin g limited by the nuts 0 on said pins 0.

The rotating ring or sleeve G is splined to and rotated by a rotating shaft G, journaled in suitable bearings G on the frame of the machine and G on the slide 0. The seaming-roller-operating head His secured fast to the shaft G and moves up and down with it. The shaft G. is furnished with a collar 9 that engages the slide 0, so that the shaft G and the head H will be forced down by the movement of the slide. A coil-spring G is insertedbetween the sleeve or ring G and a shoulder g on the shaft G, so that said ring G will be forced down with the shaft G, while permitting the ring G to be lifted or raised by the clamping-ring B independently of the head H and shaft G. V

The slide 0 is automatically moved up and down as required by means of a cam K on the shaft K through a connecting-lever K pivoted at K to the frame and having a slotted connection K with the slide 0. The lever K may be provided with a treadle-arm K to enable the slide to be operated by the foot, if desired.

M is the driving-shaft, around a pulley m on which a belt 'm' passes to a pulley G on the shaft G to rotate the same.

Motion is communicated to the cam-shaft K from the driving-shaft M through a pulley m on said shaft, belt m and pulley m on counter-shaft m which is furnished with a gear m", that meshes with a gear m", loose on the shaft K, and which is provided with a clutch member m that is engaged by a sliding clutch pin or member m on the clutch sleeve or 001- lar m that is fast on the shaft K. After the shaft K makes one complete revolution the sliding pin or clutch member m is withdrawn from the clutch member m by a camlever m, pivoted to the frame at m and which is connected by a link m with the clutch-operating hand-lever m. p

P is the lower chuck-disk, upon which the can X rests while being operated upon. It is mounted upon an adjustable slide P, that can be set in any position desired to accommodatedifferent sizes of cans by the adjustin g-screw P The operation of the'machin'e is as follows: The can X being placed upon the chuck-disk P, the operator moves the clutch-lever m with his hand, thus raising the clutch cam or lever m and permitting the tWo parts or members of the clutch to engage, thus giving the cam K one revolution, and thereby automatically moving the slide 0 down until the openingand-closing clamping-ring B surrounds the upper end of the can, as illustrated in Fig. 4:, at which time the-opening-an d-closin g parts of the clam pin g-rin g are automatically closed or clamped around the can by the action of the cam-lever D, and then the further downward movement of the slides O and the shaft G forces the seaming-rollers F into position against the flange 0c of the can-cover, thereby seaming the cover on the can, as illustrated in Fig. 7. The further rotation of the cam K causes the slide 0 to withdraw, the first operation of the withdrawal being to lift the head H and the ring or sleeve G, and thus release the can from the pressure of the'seamin g-rollers,and then to open and lift the clamping-ring from the can. When the cam K finishes its revolution, its shaft K is automatically disengaged from the driving-gear by the opening of the clutch through the agency of the cam-lever m, and then another can may be placed in the machine and the operation repeated.
